Guy Harris 1f5f63f8ef Generalize wtap_pkthdr into a structure for packet and non-packet records.
Separate the stuff that any record could have from the stuff that only
particular record types have; put the latter into a union, and put all
that into a wtap_rec structure.

Add some record-type checks as necessary.

Guy Harris 8aa14236f8 Have the frame_tvbuff.c routines not use the global cfile.
Have the routines that create them take a pointer to a struct
packet_provider_data, store that in the tvbuff data, and use it to get
the wtap from which packets are being read.

While we're at it, don't include globals.h in any header files, and
include it in source files iff the source file actually uses cfile.  Add
whatever includes that requires.

Guy Harris 797d2f6a87 Move the frame_set stuff back into the capture_file structure.
libwireshark now expects an epan_t to be created with a pointer to a
"packet provider" structure; that structure is opaque within
libwireshark, and a pointer to it is passed to the callbacks that
provide interface names, interface, descriptions, user comments, and
packet time stamps, and that set user comments.  The code that calls
epan_new() is expected to provide those callbacks, and to define the
structure, which can be used by the providers.  If none of the callbacks
need that extra information, the "packet provider" structure can be
null.

Have a "file" packet provider for all the programs that provide packets
from a file.

Guy Harris 1834dca365 Move the parts of a capture_file used by libwireshark to a new structure.
Embed one of those structures in a capture_file, and have a struct
epan_session point to that structure rather than to a capture_file.
Pass that structure to the routines that fetch data that libwireshark
uses when dissecting.

That separates the stuff that libwireshark expects from the stuff that
it doesn't look at.

Have cfile.h just incompletely declare the structure and include it

Gerald Combs bebb63bea9 Keep comments from stealing hierarchy statistics.
If a packet has a comment, the Protocol Hierarchy Statistics dialog will
add its stats to a top-level "Packet comments" node instead of the
"Frame" node. Add a check for the pkt_comment protocol ID and skip over
it if we find it. Affects Wireshark 2.0, 1.12, 1.10, and probably
earlier versions.

As an alternative we could always force "Frame" to be the first item in
the tree.

Guy Harris 0734ac385f Rename buffer_ routines to ws_buffer_ to avoid name collisions.
In particular, epan/wslua/lrexlib.c has its own buffer_ routines,
causing some linker warnings on some platforms, as reported in bug
10332.

(Not to be backported to 1.12, as that would change the API and ABI of
libwsutil and libwiretap.  We should also make the buffer_ routines in
epan/wslua/lrexlib.c static, which should also address this problem, but
the name change avoids other potential namespace collisions.)
